Bigger numbers are faster right? In a normal world, this comparison would be a no-brainer. To surpass the abilities of their latest models, John Hennessey and his team have been tinkering with a Long Tail. To see if it can perform with the latest Super Series, this is the Hennessey McLaren 600LT vs a stock 720S.

Starting at the most important specs, the 600LT is the grand finale for their 3.8L V8. It offers 600 horsepower and 457 lb-ft of torque. After installing larger downpipes and a tune, it is now making 658 horsepower at the rear wheels.

The opponent sports their latest 4.0L V8, which is bored & stroked to spool the turbos at an early RPM. Tell us what you think in the comments below, and stay with us for the latest Hennessey Performance updates.
